The NPi®-200 Pupillometer System Integration Overview

The NPi-200 Pupillometer System is a point-of-care device, however the pupillometer does not facilitate transmission of patient data into an EMR, it is not connected to an EMR, and it will not be connected to your hospital’s network. The patient information (pupil measurement data) is contained on the patient-specific disposable SmartGuard® product that has an embedded RFID smart card memory tag.


The patient data on the SmartGuard is not able to be exported in HL7 protocol. As with all other point-of-care devices (ie: ventilators, glucometers, etc.) whose biometric feeds or patient data must be converted into HL7, the patient’s pupil measurements contained on the SmartGuard must also be converted into HL7 to upload into your EMR. To facilitate transmission of the patient data on the disposable SmartGuard into any EMR system, it will require a device driver provided by a third party (ie: Capsule Technologies, iSirona/Nanthealth, Cerner, etc.) of which will be specified by you and your IT department.

Our Technology

The NPi-200 Pupillometer System uses RFID (radio frequency identification) technology to transfer data between the pupillometer and the SmartGuard®. RFID facilitates data collection at high speed using low wattage (13.56 MHz) radio frequency to read from and write to the SmartGuard memory. Incorporated into the design of the NPi-200 Pupillometer is a radio frequency (RF) antenna which broadcasts patient data information to the SmartGuard.
